Enterprise software companies spend a very small amount on R&D. Usually < 15%: http://www.zdnet.com/r-and-d-spend-critical-but-no-fixed-for...
I didn't really think of New Relic as "Enterprise Software". They are a SaaS Company. Most of the reason enterprise software has so little R&D is because they spend all their resources customizing deployments for enterprise customers.
i think enterprise and SaaS are orthogonal descriptions. new relic is definitely enterprise - as opposed to consumer (ala, dropbox). That their product is a SaaS offering doesn't really make any difference.
You're talking about two different dimensions.
Enterprise and consumer run along one axis (B2C vs B2B), self-serve vs custom deployment on the other axis (low friction vs high friction)
Much of the innovation we've seen in B2B has not just been the consumerization of the interface but also the move to self-service models.
It's you. For all the large and growing enterprise software companies you're going to see very heavy sales & marketing.
For example, Zendesk was nearly identical: http://www.sec.gov/Archives/edgar/data/1463172/0001193125141...
They spend as much on General Administrative as they do on R&D and they spend 3.6x , more on marketing and sales then they do on R&D.
